InCoax GoCA System
InCoax GoCA solution consists of three main system components, the subscribers Coax Access Modem (CAM), the in-building fiber to coax bridge, Coaxial Link Controller (CLC) and the management system, Coax Link Manager (CLM).
The CLC acts as a bridge between the incoming fiber and the in-building, or local area, coax network. To facilitate tailor-made solutions for different building sizes there are different models, with various capacities, to choose from. The choice depends on the number of subscribers, services and broadband capacity required.
The different models of the CLC have a different number of RF connectors, one channel each. The RF channels can be mixed together, using diplexers, which also connects the CLC signal to the in-building cable-TV network. This gives a great flexibility in assigning fast broadband capacity to different parts of the in-building coax network.
In the apartment, the subscriber connects a home modem (CAM) to the existing cable-TV outlet, and the TV set to the modem, using a standard antenna cable. The CAM has four Ethernet ports, intended for different, operator-defined, services, like IPTV, VoIP and high-speed Internet.
Since InCoax uses free capacity in the coax network, above the cable-TV spectrum, GoCA doesn’t affect existing cable-TV distribution in any way.
In certain systems, to bridge cable-TV line amplifiers, it may be necessary to add signal repeaters, Coax Link Repeater (CLR).
The management system, CLM, is used to set system parameters in the CAM, CLC and CLR, and to monitor the local system and its traffic parameters. The management system is normally located in the operator's NOC (Network Operation Centre).
